An Experimental Study on Mechanical Properties of Metakaolin Based Concrete with Addition of Fibers

Abstract

The main aim of this paper is to study the mechanical properties of metakaolin based concrete with addition of fibers. The project is divided into two phases, in first phase cement is replaced with metakaolin in the variations of 5%, 10%, 15% and 20% by weight of cement, then it is tested for its workability and mechanical properties on fresh and hardened concrete. In the second phase of the project fibers like Sisal (natural) and Concrix (artificial) are added to the optimum strength mix of metakaolin based concrete in the percentages of 0.25%, 0.50%, 0.75% and 1% separately (by weight of cement). Then the fibre concrete is studied for its fresh and mechanical properties. Finally, the fibre concrete test results are compared with conventional concrete.
